Abstract
Fahrzeugsitz, insbesondere Nutzfahrzeugsitz, mit einem in einer Hauptschwingrichtung (z) schwingfähigen Scherengestell (3), welches einen Oberrahmen (7), zwei erste Schwingen (8a) und zwei zweite Schwingen (8b), die sich paarweise an einer in Sitzquerrichtung (y) verlaufenden Scherenachse (10) kreuzen, aufweist, wobei die beiden ersten Schwingen (8a) an einem Ende mittels eines in Sitzquerrichtung (y) verlaufenden Querrohrs (18) miteinander verbunden sind, das mittels wenigstens einer Lagervorrichtung (20) am Oberrahmen (7) drehbar gelagert, welcher mittels wenigstens einer Schwingvorrichtung (25) relativ zum Querrohr (18) in Sitzlängsrichtung (x) schwingfähig ist, dadurch gekennzeichnet, dass die Horizontalschwingungen des Oberrahmens (7) in Sitzlängsrichtung (x) bei kleinen Auslenkungen durch die Schwingvorrichtung (25) ungedämpft und bei großen Auslenkungen durch die Lagervorrichtung (20) gedämpft sind.Vehicle seat, in particular utility vehicle seat, with a scissors-type frame (3) capable of oscillating in a main direction of vibration (z), which has an upper frame (7), two first wings (8a) and two second wings (8b) arranged in pairs in a seat transverse direction (y) the two first rockers (8a) are connected at one end by means of a transversely extending in the seat transverse direction (y) cross tube (18) which by means of at least one bearing device (20) on the upper frame (7) rotatably which is oscillatable by means of at least one oscillating device (25) relative to the cross tube (18) in the seat longitudinal direction (x), characterized in that the horizontal vibrations of the upper frame (7) in the seat longitudinal direction (x) with small deflections by the oscillating device (25) unattenuated and are damped at large deflections by the bearing device (20).
Description
Die Erfindung betrifft einen Fahrzeugsitz, insbesondere Nutzfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a vehicle seat, in particular a utility vehicle seat, with the features of the preamble of claim 1.
Ein durch Benutzung bekannter Fahrzeugsitz dieser Art weist als ein viskoelastisches Element einen Querstab auf, welcher endseitig am Oberrahmen und mittig am hinteren Querrohr befestigt ist, um Schwingungen des Scherengestells in Sitzlängsrichtung zu dampfen. Aus der nachveröffentlichten

Der Erfindung liegt die Aufgabe zu Grunde, einen Fahrzeugsitz der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is based on the object to improve a vehicle seat of the type mentioned. This object is achieved by a vehicle seat with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
Aufgrund der Schwingvorrichtung kann das Scherengestell Schwingungen in Sitzlängsrichtung, d. h. Horizontalschwingungen des Oberrahmens relativ zum Querrohr, aufnehmen, die bei kleinen Auslenkungen ungedämpft sind und erst bei großen Auslenkungen durch die Lagervorrichtung zwischen Oberrahmen und Querrohr gedampft werden. Dies steigert den Sitzkomfort, indem der Insasse von Kraftstößen auf das Sitzgestell isoliert wird. Um bei großen Kraftstössen die Auslenkungen sanft zu beschränken, wirkt die Lagervorrichtung dampfend.Due to the oscillating device, the scissors frame vibrations in the seat longitudinal direction, d. H. Horizontal vibrations of the upper frame relative to the cross tube record, which are undamped with small deflections and are steamed only with large deflections by the bearing device between the upper frame and cross tube. This increases seating comfort by isolating the occupant from impacts on the seat frame. In order to gently limit the deflections in the event of large force impacts, the bearing device has a steaming effect.
In einer konstruktiv einfachen Ausbildung weist die Schwingvorrichtung vorzugsweise einen Anker auf, der mittels Federn aufgehängt ist. Der Anker ist vorzugsweise am Querrohr angelenkt, so dass die Federn zwischen Anker und Oberrahmen wirken. Die Lagervorrichtung weist in konstruktiv einfacher Ausbildung eine Führung mit einer Führungsbahn für das Querrohr, vorzugsweise für eine Lagerrolle des Querrohrs auf. Eine Dämpfung, d. h. Energiedissipation, erfolgt vorzugsweise mittels Endanschlägen der Lagervorrichtung, die vorzugsweise aus einem Elastomer gefertigt sind. Die Führung kann als weitgehend geschlossene Einheit mit Führungsbahn und Endanschlägen im Inneren ausgebildet sein, in welche das Querrohr durch eine Öffnung hineinragt. Eine solche Lagervorrichtung kann an beiden Enden des Querrohrs vorgesehen sein.In a structurally simple embodiment, the oscillating device preferably has an armature which is suspended by means of springs. The anchor is preferably articulated on the cross tube, so that the springs act between the anchor and the upper frame. The bearing device has a structurally simple design a guide with a guideway for the cross tube, preferably for a bearing roller of the cross tube. A damping, d. H. Energy dissipation, preferably by means of end stops of the bearing device, which are preferably made of an elastomer. The guide may be formed as a largely closed unit with guideway and end stops in the interior, in which the cross tube protrudes through an opening. Such a bearing device may be provided at both ends of the cross tube.
Wenn in Abhängigkeit von der Fahrsituation keine Schwingungsisolierung gewünscht ist, kann mittels einer Verriegelungsvorrichtung das Querrohr mit dem zugeordneten Oberrahmen verriegelt werden, worauf die Horizontalschwingungen unterdrückt werden. Vorzugsweise ist hierzu ein Verriegelungshebel vorgesehen, welcher vorgespannt und mittels beispielsweise eines Bowdenzuges schwenkbar ist.If, depending on the driving situation, no vibration isolation is desired, the transverse tube can be locked to the associated upper frame by means of a locking device, whereupon the horizontal vibrations are suppressed. Preferably, a locking lever is provided for this purpose, which is biased and pivotable by means of, for example, a Bowden cable.
Der Begriff ”Querrohr” soll nicht auf kreisförmige Querschnitte und auf hohle Profile beschränkt sein, sondern allgemein das die Schwingen verbindende Bauteil (oder ein damit wiederum verbundenes Bauteil, beispielsweise ein Zapfen in Sitzquerrichtung) bezeichnen. Die Kombination von Lagervorrichtung und Schwingvorrichtung kann statt zwischen Oberrahmen und Querrohr alternativ oder zusätzlich zwischen Unterrahmen und Querrohr vorgesehen sein. Die Lagervorrichtung ist vorzugsweise auf beiden Fahrzeugsitzseiten, die Schwingvorrichtung vorzugsweise auf genau einer Fahrzeugsitzseite vorgesehen.The term "cross tube" is not intended to be limited to circular cross-sections and to hollow profiles, but generally designate the component connecting the wings (or a component, in turn, a connected component, for example a pin in the seat transverse direction). The combination of bearing device and oscillating device may alternatively or additionally be provided between the subframe and cross tube instead of between the upper frame and cross tube. The bearing device is preferably provided on both vehicle seat sides, the oscillating device preferably on exactly one vehicle seat side.
